Volcano Watch: Kilauea activity update for week of Jan. 1

(Activity updates are written by scientists at the U.S. Geological Survey’s Hawaiian Volcano Observatory.)

Lava stopped entering the ocean entry at the Waikupanaha, west of Kalapana, early last week as the lava supply from the TEB vent dwindled. Small lava flows were active above the pali starting mid-week.

Glow above the collapse pit inset within the floor of Halemaumau Crater, at Kilauea’s summit, has been bright at night from the Jaggar Museum this past week.  The lava surface deep within the collapse pit has been fluctuating in height, episodically rising up to form a small lava pond at the bottom of the pit.

This activity has been visible, primarily at night, in the Webcam perched on the rim of Halemaumau.  Volcanic gas emissions remain elevated, resulting in high concentrations of sulfur dioxide downwind.

One earthquake beneath Hawaii Island was reported felt during the past week. A magnitude-1.8 earthquake occurred at 10:22 p.m. Wednesday, Jan. 6, 2010, and was located 4 miles east of Captain Cook at a depth of 5 miles.
